rThe invention relates to a mounting for a sash of the swinging type.

An objectief the :invention vis to provide an improved mounting for a swingable sash havinga weather ilange engage-able against the outer side of a window casing, said mounting having no parts thereof protrude from the Window A.opening or casing.

Another object of the invention is yto pro.- vide a -mounting-'of the class described which is automatically#operative'to elfect a resilient engagementof the weather' liange with the casing when-the sash is in closedfposition.

A further object ofthe invention is t'ofprovide amounting means or" .the-,class described in which.provisionisimade Ifor the adjustment of the sash with `respect vto the `mounting whereby the resilient engagement of the weather :flange with lthe casing may be assured.

The invention possesses i other i objects .and features of advantage, someof which, with the foregoing, will beset yforth inthe :following description of the preferred Vform `ofthe invention which is illustrated in-the drawings accompanying and formingpart of the specification. It is to be understood, however, that variations inthe showing made by the said drawings and description may be adopted within the scope oif the invention as set forthinzthe claims.

Referring to said drawings,V

Figure 8 is an enlarged perspective fragmentary view showing a modilication oif the structure shown .in Figures l to G.

As particularly .illustrated in Figures 1 to G of the drawings, the invention yis applied in effecting a swinging mounting of a metal sash 14 `in a metallic window-trame 16. The frame k16 is here shown formed of members -17 oflfbeain section having one 'flange 18 defining the front of thefframe as a 'casing mem berftherefor, .with the webs y19 of theanembers cooperating with the `iront ianges 18 and the reariiianges 21 to define a channel 22 within the area-,oi2 the `frame. The sash k1Ll,`it is noted, is lformed with stiles 23 .of right-angled Z section, said stiles being fixed together in such ,relation that-the ywebs 24`tliereoi define the pane receiving opening of the sash, and flanges 26 extend youtwardly therefrom as lateral extensionsat one face'oic the sash. The area defined Vby the outer edges of the sash flanges 26 .exceeds that of the area defined .within casing flanges 18 whereby, when the sash is disposed in closure .relation in the window frame,the rear surfaces of the flanges 26 will engage flat .against the outer faces oi' the. casing members 18 or" the tframe. As particularly shown,athe Aframe members I17 are integrally joinedat theirpoints of abutment todeiine-an integral 'rameofiixed size, and the sash stiles 23 are similarly joined to provide aiunitary sash structure.

In the present emb0diment,.the sash is pivotally'mounted on and between upper Iand lower .shoes v27 .and28 Aarranged for slidable movement along theupper and lower frame .channels 22 inguideways 29 provided therein, -thepivotalmovement of the sashv thus y being V,arranged .to vtake place 1 about e a vertical axis. The. shoes 27 and 28 are of similar but opposite Vstructure whereby corresponding parts thereof` maybe in opposition `when the shoes of a pair are disposed in their respec Cil) bearing surfaces 34 and for guiding the movement of a shoe along the track. The

tracks 3l, it is noted, extend from one end of the channels toward, but not to, the other 7 ends thereof.

Each of t ie shoes, it will now be noted, is of rectangular outline and opposite side edOes 37 and 38 thereof are arranged to be disposed in opposition to the guideway bear- 1 ing surfaces 3d and 36 respectively when the shoe is engaged with the track. Means are provided for urging the shoes inwardly in the guideways and against the surfaces 34 thereof, and in the present instance such means comprise fiat springmembers 39 having an extremity thereof protruding from the shoe edge 38 to provide a projection ll for constant engagement against the guideway bearing surface 36 wherebv the shoe is constantly urged toward the guideway surface 3i. As shown, the springs B9 are generally U-shaped and are carried in grooves l2 proided in the inner surface of the slices, and the spring projections 41 preferably lie adjacent one end of the shoe, Bearing blocks 43 are mounted on the shoe edges 37 at opposite ends thereof, such blocks preferably being of less height than are the shoes whereby their outer edges l-l provide coplanar bearing sur- ;v, faces inwardly of the outer surface of the shoes for engagement beneath flanges 45 extending forwardly from the edges of the channel flanges 3Q to closely overlie the blocks. ln this manner, the shoe is arranged to be held against lateral removal from the guideway and the latter need extend no further from the frame webs 19 than do the shoes. As particularly shown` a shoe is formed by appropriately shaping a blank of sheet metal, the blank portion providing the rear edge 37 of the shoe being bent back upon itself to provide the blocks 43 of the shoe. rfhe inner end of the spring 39 is also fixed to the shoe portion providing the shoe edge 37 whereby the spring is movable with the shoe, it being noted that the shoe formed as dcscribed is generally channel shaped'in transverse section with the longitudinal channel thereof providing the spring` groove 42.

Pivoted to the shoes 27 and 2S by means of pivot pins 4G are members .i7 and 48, said members being arranged for attachment to the sash stiles adjacent the top and bottom of the sash whereby the sash is arranged for pivotal movement about an axis perpendicular to the tracks 3l. Preferably, and as shown, the pivot pins 4G are disposed adjacent the same shoe ends as are the spring projections 4l. The member 47, it is noted, is generally L-shaped, one arm 49 thereof being perforated to receive the pin 46, while the other arm 51 thereof is arranged for mounting along and against the outer side of the web 2a of a side stile 23. rl`he plate arm 5l and web Qt are provided with pairs of registering perforations for the reception of bolts for clamping the arm and web together. Preferably, the perforations 52 of the arm 5l are in the form of slots extending longitudinally of the arm whereby the pivotal axis provided is adjustably shiftable in the plane of the sash, and at least one slot of a pair wider than need be for receiving a fastening bolt whereby said pivotal axis is also transrersely shiftable with respect to the plane of the sash flanges 26. in this manner, all necessary adjustability of the relation of said pivotal axis to the sash is provided for.

The member 48, it will now be noted, is geiierally straight with one end thereof perforated for receiving the pivot pin 4G and the other end ixcdly disposable against and beneath the web of the lower sash stile. The member 48 and the web of the lower sash stile are provided with pairs of registering` perforations 56 and 57 respectively for the reception of bolts 58 by means of which the member 48 is fixed to the stile web. Means are provided for adj usting the pivotal axis provided by the member 48 in a direction transverse of the plane ofthe sash flanges 26, and as shown, such means comprises the format-ion of a. perforation 5G in the form of an arcuate slot having the other perforation 5G as its axis of curvature, the degree of adjustment provided corresponding in direction and amount to the similar adjustment provided for the member l-7. lio other adjustment is provided for the member 'l'w', as such will not generally be necessary.

Similarly disposed linlfs 5S) are connor-tial between intermediate points of the top and bottom .we i st iles to points of the upper and lower ,me members not occupied by dal tracks li and are pivotally connected to ine il and Z-r of the frame n'leinbers l'i' "les 23 respectively. rl`he area defined by il e stile webs l), it is noted, is enough smaller than that defined within the frame fianges or casings 18 to permit the disposal of the links 59 between the frame members and sash when the latter is in its closed position, the links being appropriately mounted on brackets (il and (32 formed to permit this disposal. of the links.

lt will now be noted that mmxelnent of the shoes along the tracks will variously pnsition the ash with respect to the fra ie opening and that when the shoes have assumed one extreme position thereof adjacent tb(k side frame member 6?) at the end of the track 3l, the sash is arranged to be in closed position. It is noted, however, that as the sash flange G4 which is arranged to come to rest in overlying relation in front of the casing portion 66 provided .by the member 63 moves toward the member 63 as vthe window is closed, its edge lies .appreciably inwardly of the frame .flange 18 providing -the casing portion 66 .and would catch therebehind if not shifted forwardly as the sash is further closed, this condition .being particularly brought out in Figure 3, and means are accordingly provided for effecting such displacement of `thesash as it is moved to closed position as will so dispose the flange 64e as to permit the closing ofthe sash. As shown, the latter means comprises the provision of one or more strikes 67 mounted on the frame member (53 and presenting oblique guide faces 70 disposed in the path of movement of the sash flange edge and terminating at the front face of the casing 63.

The displacement of the sash flange Get out of its normal path by means of the strikes 67, it will now be noted, may only be edected if a sufficient forward movement of the shoes 27 and 9.8 is permitted. Yet to prevent a.

Y rattling and general loosen-ess of the sash when in an open position, the shoes should be substantially the same width as the guideways 29 provided therefor and the necessary forward displacement thereof would not then be permitted,itbeingclear that such displacement need be provided for only as the fully closed position of the sash is approached. Accordingly, and as showin'a portion 68 of the bearing surface 3G of each track fla-nge 33 adjacent the member 63 is offset forwardly to permit .the necessary forward movement of the shoe against the resistance of the spring 39-as shown, this is accomplished by offsetting the track flange itself whereby the track may be formed by appropriately shapingl she-et material. Preferably, .and as shown, the widened track portions are Vvof such length that .the shoe ends which do not carry the pivot pins i6 never lie therein. In this manner, forward displacement of the shoes is arranged to be pivotal and about the shoe. portions which remain engaged in .the narrower track portion.

It will now be noted that as a. shoe advarices into the wider track portion it will maintain its engagement against the forwardly directed track bearing surface 32 by reason of the `extension of the spring 89 to effect an engagement with the surface 68 until a strike is reached by the sash flange 64, after which the sash and shoe will be swung forwardly as described. cSubstantially as the flange 64 first reaches the outer surface of the casing 66, the shoe will have been swung to its most forward position, and continued closing of the sash will `thereafter permit the inward movement ofthe shoe back toward the bearing surface To insure the maintenance of a tight closingl engagement of the sash flange 64 with the ca.. ng portion 6G, it is desirable that the swinging shoe end be not permitted to engage thebearplane of the flange permits a setting of the members 1 7 and Ll-.8 toprevent such engagement. In this manner, the springs 39 are freely operative to resiliently urge the flange 6a to maintain a seated engagement with the casing 66, it being noted that the adjacent portions of the .top and bottom flanges of the sash are also rcsi'liently held against the opposed casing portions. y

To permit the movement of the sash new described, the sash flanges are appropriately notched at the top and bottom thereof, as at 69, edges 71 of the notches being engageable with the top and bottom casings 18 when the sash is reversedly disposed .to provide a stop for the sash. Notc'hes 72 are provided along the front track flange 33 whereby the spring projection l1 may engage therein .to hold the sash in a plurality of set open positions. .At least for the lower track, notches 7 3 registering` with the track notches 7 2 are provided in the opposed casing, whereby the casing channel and the shoe guideway may` be drained of any wat-er collecting therein.

In the embodiment disclosed in Figure 8, the provision of means permitting the necessary forward swinging of a sash carrying shoe, as the sash is closed, is vincorporated entirely in the shoe structure. In this embodiment, like track members 81` are mounted in the channels of the top and bottom frame members 17, said tracks providing guideways 82 of uniform width., The Vshoes 83 are formed generally similarly to the shoes of the first described embodiment, except that the present shoes are tapered toward the pivot carrying ends thereof to permit a. forward swinging of said ends about their wide ends when the sash flange 6a engages the strikes 67. Vlie-n the tracks 81 and shoes 83 are used, the samel operative relations between the sash 14: and frame 16 obtain as before. In the present embodiment, an outward displacement of the. pivot carrying end of the shoe is, of course, permitted in all' positions of the shoe, while in the first embodiment, such movement is permitted only as the sash closes.

'lhile the mounting of -my invention is here shown and described as particularly applied to mounting` a sash for pivotal movement about a vertical axis, it will be clear that the same mount-ing may be utilized in securing a sash for pivotal movement about a horizontal aXis. In the latter event, a pair of complementary members 47 might be used at opposite ends of the. same sash stile for securing the sash to the shoes, it being particularly noted that the use of the member 48 `at the bottom of the sash in the present embodiment causes the weight of the sash to operate transversely of the member 48 and so does not tend to alter the adjusted mounting of the member on the bottom sash stile.
